Molecular orientation methods using parallel polarized nonresonant two-color laser pulses have been proposed and demonstrated. In the method, the anisotropic hyperpolarizability interaction with the two-color fields is exploited. Recently, we have proposed some strategies to improve molecular orientation by optimizing relative delay and intensities of two-color laser pulses. In the present work, we demonstrate that two-color fields with orthogonal polarizations can improve the adiabaticity of the orientation dynamics, leading to higher degrees of orientation compared to the parallel polarized two-color fields.
